L2TP connecting but not assigning IP
I have an USG 110 with the newest firmware and I setup a L2TP VPN.
I have following problem, two laptops (both Microsoft Surface) are working perfectly with the VPN.
But with all other Windows 10 (1909), I have a problem. Within the Zyxel VPN monitor I can see that this PC's can connect. But they don't get an IP address.
And after a short time the PC's disconnect and get different errors, mostly 718 or 829.
I also tried the NAT regedit hint, but it doesn't work.
Do you have an idea?
